    Abstract: A cluster isolation system includes a processor that is operatively coupled to an input device, an output device, and memory. The system determines feature/interval combinations that distinguish one cluster of data objects from other clusters. The processor calculates cluster isolation measurement values at selected cut-off values for each feature. The processor reports the features and feature score intervals that satisfy selected isolation measurement value thresholds.
